Judging by your question, you have a local file you want to send to the destination server. So you have the right syntax which is good!

If you're getting permission denied, then you're not using the correct username or something's amiss with the authentication. Most likely, it's because the sudo command only works locally, for starters, so it won't give you root on the remote box, so that's probably the problem. Make sure that the user you are logging in as on the remote server has write permissions to the location you're trying to write to.

If the problem is the destinationuser doesn't have access to that location without sudo, move the file to the destinationuser's home folder then sudo mv the file from the shell on the other server to put it in the right location.

Had the same problem. I found out that the directory containing my source file did not have enough permission. So I just changed the mode recursively using:chmod -R 771 directory_path on the source machine.

This error occurred for me when the file already existed in the target location and the existing file had read-only permissions (preventing the file from being overwritten). In my case, I just logged in and deleted the existing file and that corrected the problem.
